Description
Technical field
This utility model is related to continuous casting installation for casting technical field, more particularly to a kind of middle water containing opening shutter machine
Structure.
Background technology
The technique of the continuous casting of steel mill commonly used multimachine multithread now carries out producing strand, during continuous casting often
The exception of production development or equipment needs disconnected wherein certain one stream of lock and ensures that normally drawing of other streams is poured, a lot of in order to ensure quality
Steel mill adopts submersed nozzle and plug rod mechanism in addition flow control, once plug rod mechanism fault or stopper head are corroded by molten steel leading
Cause cannot completely cut through steel stream and cause major accident, and present way is by middle water containing opening flashboard structure, steel stream to be hindered
Disconnected, belong to the safety equipment on a kind of tundish, ensure production safety.Current continuous casting intermediate inlet guillotine mechanism is mainly wrapped
Include mechanism body and flashboard, mechanism body is connected with tundish inclusion with otic placode by bolt, this fit system has one
Fixed gap, and during oil cylinder pushing flashboard lock breaks casting stream, guillotine mechanism can be caused with very big impulsive force, break in lock in the mouth of a river
Still molten steel flows down afterwards, damage equipment, and flashboard needs and high-temperature molten steel directly contact, the easy temperature distortion of general steel；Ash casting
Ferrum heat resistance is poor, is easily punctured by molten steel during use；Though will not be by high-temperature steel water attack using resistant to elevated temperatures heat resisting steel
Wear, but heat resisting steel quality is more crisp and not easy processing；Although also there being all good heat resisting steel of thermostability and processing characteristics, cost is held high
Expensive, cost is very high.
The patent application of China Patent Publication No. 2717573（The day for announcing is August in 2005 17, in the middle of entitled continuous casting
Bag emergency gate flashboard）Disclose the flashboard after a kind of improvement, using substrate with inlay plate and combine combinative structure body,
The flashboard combining both had met the requirement of the aspects such as structural strength and heat resistance.In order to avoid coming off, a combination thereof mode is
The mode of welding, bonding or casting, so inlay plate or remove original elbow-board when needing to reconfigure in replacing number
Tired.
The patent application of China Patent Publication No. 201357215（The day for announcing is on December 9th, 2009, in entitled continuous casting
Between bag emergency gate mechanism）Disclose a kind of guillotine mechanism, including strengthening steel plate and the body of resistance to material, strengthen steel plate and the body of resistance to material, plus
Strong steel plate is located at the bottom of little perforate, and is welded and fixed with mechanism body phase, and the body of resistance to material is cast on reinforcement steel plate, this shutter machine
Structure passes through setting reinforcement steel plate and reinforcing mat can greatly improve the intensity of flashboard, but complex manufacturing technology and the resistance to material of replacing
The operation of body is also relatively cumbersome.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of middle water containing opening flashboard for above-mentioned prior art
Mechanism, this guillotine mechanism includes mechanism body and flashboard, and structure is simple, is conducive to raising lock to break and casts stability and the disconnected casting of lock of stream
